Handbook of Sharing Confidential Data : Differential Privacy, Secure Multiparty Computation, and Synthetic Data

Statistical agencies, research organizations, companies, and other data stewards that seek to share data with the public face a challenging dilemma. They need to protect the privacy and confidentiality of data subjects and their attributes while providing data products that are useful for their intended purposes. In an age when information on data subjects is available from a wide range of data sources, as are the computational resources to obtain that information, this challenge is increasingly difficult. The Handbook of Sharing Confidential Data helps data stewards understand how tools from the data confidentiality literature―specifically, synthetic data, formal privacy, and secure computation―can be used to manage trade-offs in disclosure risk and data usefulness.

Key features:

• Provides overviews of the potential and the limitations of synthetic data, differential privacy, and secure computation

• Offers an accessible review of methods for implementing differential privacy, both from methodological and practical perspectives

• Presents perspectives from both computer science and statistical science for addressing data confidentiality and privacy

• Describes genuine applications of synthetic data, formal privacy, and secure computation to help practitioners implement these approaches

The handbook is accessible to both researchers and practitioners who work with confidential data. It requires familiarity with basic concepts from probability and data analysis.

Jörg Drechsler is Head of the Department for Statistical Methods at the Institute for Employment Research in Nuremberg, Germany, and Professor of Statistical Science at the Institute for Statistics at the Ludwig-Maximilians-University in Munich. He is also Associate Research Professor in the Joint Program in Survey Methodology at the University of Maryland. His main research interests are data confidentiality and nonresponse in surveys. He is a fellow of the International Statistical Institute. He received his PhD in Social Science from the University of Bamberg and his Habilitation in Statistics from the Ludwig-Maximilians-Universität in Munich.

Daniel Kifer is Professor of Computer Science at Penn State University. He has published extensively on technical approaches for privacy and confidentiality, with work spanning attack algorithms, novel methods for disclosure avoidance, statistical analysis of perturbed data, and automated tools for catching implementation errors. In 2016–2017, Kifer spent his sabbatical at the U.S. Census Bureau and helped design the disclosure avoidance system used for the 2020 Decennial Census. Kifer obtained his bachelor’s degrees in mathematics and computer science at New York
University and his PhD at Cornell.

Jerome Reiter is Professor of Statistical Science at Duke University. His primary research areas include methods for protecting data confidentiality, for handling missing values, and for integrating data across multiple sources. He has worked extensively on theory, methods, and applications for synthetic data. He is Fellow of the Institute of Mathematical Statistics and the American Statistical Association. He received a PhD in statistics from Harvard University and his undergraduate degree from Duke University.

Aleksandra Slavkovic is Professor of Statistics & Public Health Sciences, Dorothy Foehr Huck and J.Lloyd Huck Chair in Data Privacy and Confidentiality, and Associate Dean for Research, Eberly College of Science at Penn State. Her research focuses on methodological developments in the area of data privacy and confidentiality in the context of small- and large-scale surveys, health, genomic, and network data, including work on differential privacy and broad data access that offers guarantees of accurate statistical inference needed to support reliable science and policy. She is Fellow of the American Statistical Association, the Institute of Mathematical Statistics, and the International Statistical Institute. She received her PhD (2004) and MS (2001) in statistics and Master of Human-Computer Interaction (1999) from Carnegie Mellon University. She received her BA in psychologyfrom Duquesne University (1996).
